Built for one of Volvo’s largest wheel loaders, this Tilt Cylinder Seal Kit is engineered specifically for the L330D — a machine that regularly handles 5+ ton bucket payloads in quarries, mines, and bulk material yards. The L330D’s tilt cylinder operates at higher bore diameters and sustained pressure loads than mid-size loaders, which means standard seal kits often fail prematurely under this machine’s operating demands.
This kit is manufactured to the exact tolerances of Volvo’s OEM tilt cylinder assembly, addressing the specific failure points seen in large-frame wheel loaders: seal extrusion under heavy shock loading, wiper degradation from abrasive quarry dust, and rod seal wear from continuous high-cycle tilting.
Common Signs Your L330D Needs This Seal Kit
- Visible oil film or dripping around the tilt cylinder rod after operation
- Bucket “creeping” or drifting downward when the machine is parked on a slope
- Reduced breakout force when curling a full bucket load
- Spongy or delayed tilt response during dump cycles
- Visible pitting or scoring on the exposed cylinder rod
If you’re seeing two or more of these symptoms, the seal kit should be replaced before the leak accelerates and damages the rod surface or cylinder bore itself.

Why Choose Our Volvo Seal Kits?
1. Heavy-Duty, Mining-Grade Materials
Manufactured with top-tier Polyurethane (PU) and premium NBR rubber, engineered to withstand the high shock loads, extreme friction, and wide temperature swings typical of large wheel loader operation.
2. Perfect OEM Match
Precision-engineered to match Volvo’s original dimensional tolerances exactly — no shimming, sanding, or modification needed. This ensures a seamless fit and an absolute zero-leak seal on installation.
3. Extrusion & Wear Resistance
Specially treated to resist extrusion under the high-pressure cycling common in mining and quarry environments, where the L330D’s tilt cylinder sees near-continuous use throughout a shift.
Installation Tips
- Inspect the cylinder rod surface for pitting or scoring before installing new seals — new seals installed over a damaged rod will fail quickly
- Lightly lubricate all seals with clean hydraulic oil before assembly to prevent installation damage
- Replace the dust wiper even if it appears intact — it’s a low-cost part relative to the labor cost of a repeat teardown
- Bleed the hydraulic system thoroughly after reassembly to avoid air-induced cavitation damage
Important Fitment Note
This kit is specifically designed for the TILT / BUCKET cylinder on the Volvo L330D. Please cross-check your original cylinder part number or machine serial number before ordering, as tilt cylinder specifications can vary across production years even within the same model line.
Frequently Asked Questions
Q: Will this kit fit other Volvo L-series loaders?
A: This kit is dimensioned specifically for the L330D tilt cylinder (OEM# 11107148/11709226). Other L-series models use different bore and rod diameters — check your OEM part number before purchasing.
Q: How long does a typical seal kit last in mining conditions?
A: Service life depends heavily on duty cycle and environment, but abrasive dust and high-cycle tilting in mining applications generally shorten seal life compared to general construction use. We recommend inspecting seals during scheduled hydraulic maintenance intervals.
Q: Do I need to remove the cylinder from the machine to replace these seals?
A: Yes, the tilt cylinder must be removed and the rod withdrawn from the barrel to access and replace the internal seals.
